High-current explosion-proof distribution box

High-current explosion-proof distribution boxes are designed for hazardous areas, offering modular, certified solutions capable of handling currents up to 180A with ATEX and IECEx compliance.Overview

Explosion-proof distribution boxes are electrical enclosures engineered to safely distribute power in hazardous environments where flammable gases, vapors, or dust may be present. They are commonly used in industrial plants, oil and gas facilities, chemical processing, and mining operations. These boxes are designed to prevent sparks or arcs from igniting surrounding atmospheres, ensuring operational safety and regulatory compliance .

Key Features
  • High Current Capacity: Some models, such as the CE92 series, support a main switch up to 180A and branch circuits up to 100A, suitable for heavy-duty industrial applications .
  • Modular Design: Many boxes, including GRP or stainless steel enclosures, allow customizable internal layouts, modular combination of switches, and optional components like voltmeters, ammeters, and LED indicators .
  • Materials: Enclosures are typically made from stainless steel (AISI 304L or 316L) or glass-reinforced polyester (GRP), providing durability in extreme temperatures and outdoor conditions .
  • Certifications: Certified for ATEX, IECEx, and UL, suitable for Zone 1, Zone 2, Zone 21, and Zone 22 hazardous areas .
  • Control and Monitoring: Many units integrate local control stations, motor starters, push buttons, and grounding devices, allowing safe operation and monitoring directly from the enclosure .
  • Environmental Resistance: Designed to withstand extreme temperatures (down to –40°C), humidity, and corrosive environments, ensuring reliable performance in harsh conditions .
Applications
  • Industrial Power Distribution: Safely distributing high currents to machinery and equipment in hazardous zones.
  • Remote or Automated Installations: Modular systems allow integration with UPS, transformers, and battery packs for continuous operation .
  • Custom Projects: Many manufacturers offer made-to-order solutions to meet specific operational requirements, including size, internal layout, and control elements .
Manufacturers and Options
  • BARTEC: Offers modular low- and medium-voltage solutions, including distribution boards, switchgear, and battery packs up to 40kV, with full service support from engineering to maintenance .
  • Atex Delvalle: Provides stainless steel and GRP enclosures with customizable control stations, certified for ATEX and IECEx, suitable for extreme climates .
  • Hexlonex: Durable explosion-proof distribution boxes for Zone 1 and Zone 2, IECEx and ATEX certified .
  • Warom: Modular GRP construction with external rotary actuators and optional components for flexible configurations .
  • Atex Global CE92: High-current distribution boxes with main switch up to 180A and branch circuits up to 100A . High-current explosion-proof distribution boxes combine safety, modularity, and compliance, making them essential for reliable power distribution in hazardous industrial environments.
